Natural gas hydrate is ice‐like mixture of gas (mostly methane) and water that is widely
found in sediments along the world's continental margins and within and beneath permafrost …

The deep subseafloor biosphere supports a diverse population of prokaryotes belonging to
the Bacteria and Archaea. Most of the taxonomic groups identified by molecular methods …

We investigated the frictional sliding behavior of simulated quartz‐clay gouges under stress
conditions relevant to seismogenic depths. Conventional triaxial compression tests were …

Serpentinization of mantle peridotite generates molecular hydrogen that can be exploited by
microorganisms to gain metabolic energy; however, the mechanisms that control hydrogen …

The sub-seafloor biosphere is the largest prokaryotic habitat on Earth but also a habitat with
the lowest metabolic rates. Modelled activity rates are very low, indicating that most …

Tectonic changes that produced a deep Tasmanian Gateway between Australia and
Antarctica are widely invoked as the major mechanism for Antarctic cryosphere growth and …

Most of the conceptual ideas concerning sedimentary architecture and tectonic evolution of
deep rifted margins are based on either intracontinental rift basins or proximal margins, both …

We mapped the Kane megamullion, an oceanic core complex on the west flank of the Mid‐
Atlantic Ridge exposing the plutonic foundation of a∼ 50 km long, second‐order ridge …

Paired benthic foraminiferal trace metal and stable isotope records have been constructed
from equatorial Pacific Ocean Drilling Program Site 1218. The records include the two …

Regional metamorphism occurs in plate boundary zones. Accretionary orogenic systems
form at subduction boundaries in the absence of continent collision, whereas collisional …
